Cimarron Firearms imported Uberti made cowboy action shooting version of the 1851 Richards - Mason Cartridge Conversions.- .38 Special (no + P ammo). In 1871 Colt employee Charles Richards was awarded a patent for converting 1851 Colt Navy percussion revolvers to a breech loading cartridge revolver. In 1872 William Mason, another Colt employee, was awarded a patent for an improvement to the Richards model and the 1851 Richards-Mason Conversion model revolver was born. As percussion parts ran short, the 1860 Richards-Mason barrel was changed from the earlier octagon percussion model profile to the round barreled sleek profile of the 1871-2 Open Top.

Solid, accurate and well balanced with a smooth action. A real work of art.
Practical notes:
Shoots about an inch high (said to be normal for Navy revolvers)
It has a dozen screws that need to be checked (tightened) occasionally
Easy to disassemble...Read Full Review
